        Add a test that measures the frame rate of accelerated CSS animations.

        This is like css-animation.html (which animates 'left' and 'top') but animates
        transforms instead. In order to get animation in X and Y we make two nested elements
        and set transformX() on one, and transformY() on the other.

        It should be easy to run ES6SampleBench from the jsc shell
        https://bugs.webkit.org/show_bug.cgi?id=161085

        Reviewed by Yusuke Suzuki.

        This patch makes ES6 sample bench runnable through the `jsc` shell.
        To do that, you need to be in the PerformanceTests/ES6SampleBench
        directory and run `jsc cli.js`. To make this work, the benchmark
        is now aware of being run in two modes: via the browser, and via
        the shell. Each entry point will set a variable `isInBrowser`,
        and the benchmark will do different things based on if that
        variable is true or false.

        ES6SampleBench should have a harness
        https://bugs.webkit.org/show_bug.cgi?id=159246

        Reviewed by Saam Barati.
        
        This adds a simple web harness for ES6SampleBench. It runs Air and Basic 10 times for 200
        iterations each and reports three metrics:
        
        First iteration: the time it takes for the first iteration to run. This is the first
        iteration after the benchmark is loaded into the iframe, so it's representative of what
        would happen if one of these workloads only ran for a short time.
        
        Worst 2%: of the last 199 iterations, the average of the worst 2% iterations. If code like
        any of these workloads was used in an important event handler, you'd want that code to run
        well in the worst case in addition to having great throughput.
        
        Steady state: the total of the last 199 iterations. This is representative of what would
        happen if you ran code like this for a long time.
        
        The total score is the geomean of the firstIteration/worstCase/steadyState numbers of the
        two benchmarks.
        
        The harness does statistics using Student's T-distribution confidence intervals.

        Add a ES6 generator benchmark
        https://bugs.webkit.org/show_bug.cgi?id=159101

        Rubber stamped by Keith Miller.
        
        This adds a Basic interpreter loosely based on ECMA-55:
        
        http://www.ecma-international.org/publications/files/ECMA-ST-WITHDRAWN/ECMA-55,%201st%20Edition,%20January%201978.pdf
        
        It includes a lexer that is a generator, a parser that uses regular expressions, and an AST
        walk interpreter where the walking functions for statements are generators that call each
        other with yield*. This enables the interpreter to look like an AST walk even though it can
        yield at INPUT and PRINT statements.
        
        This also uses for-of, classes, Map, and WeakMap. It also uses deprecated-but-awesome RegExp
        features like RegExp.lastMatch and RegExp.rightContext. I did it that way because this is
        how I've always written lexers in dynamic languages; see offlineasm's lex() method in
        parser.rb for example.
        
        The benchmark runs a handful of simple Basic programs. The longest-running one computes
        prime numbers.
        
        Includes a command-line and web harness. On my machine it runs in 2-3 seconds.

        Allow specifying a regression profile to use instead of taking the one
        with the lowest error.

        Address an issue in the focus test when the regression calculated ends
        up overestimating the change point, causing a cascade of tougher
        ramps. The reason behind this is that at max complexity of an initial
        ramp, the frame length is very high, and it influences the second
        segment of the piecewise regression strongly, causing it to be very
        steep. As a result, the first segment, expected to be flat, ends up
        covering a higher range of complexity. That makes the change point
        much higher than it should be. To avoid this, we will add a sanity
        check on the maximum value of the ramp. If the regression's projected
        value at the maximum complexity of the current ramp is very slow (less
        than 20 fps), 1) reduce the maximum complexity by 20%, and 2) do not
        include the regression's change point in the change point estimator.
        That estimator is used as the midpoint of the next ramp, and including
        the change point from a poor regression can bake in the error. The
        controller already knows how to adjust for ramps that are too easy for
        the system.

        * Animometer/resources/runner/animometer.js:
        (this._processData.findRegression): Takes a preferred profile and gives that to
        Regression.
        (this._processData.calculateScore): With the ramp controller, take the profile
        of the ramp that was used the most when calculating the ramp's regression. That
        profile is what is used for the test's score.
        * Animometer/resources/statistics.js:
        (Regression.Utilities.createClass): Update to take an options object which can
        specify a profile to calculate with. Otherwise it will continue to use both and
        select the one with the lower error.
        (_calculateRegression): Fix an issue where we claim 0 error if the regression
        calculation fails due to divide-by-zero. Instead reject that regression calculation
        by giving it Number.MAX_VALUE.
        * Animometer/resources/strings.js: New strings for marking a regression as flat
        or slope.
        * Animometer/tests/resources/main.js:
        (RampController): Rename the thresholds for clarity. Add a threshold that, if
        exceeded, will lower the maximum complexity of the next ramp.
        (tune): Relax the cdf check to consider whether the interval definitely falls in
        the desired frame length threshold.
        (processSamples): Include the profile in the ramp.

        Update ramp controller test. Increase the length of the test to 30 seconds, and extend
        the interval to 120 ms during sampling. Improve the estimation of the ramp parameters.

        * Animometer/developer.html: Change default to 30 seconds, and don't show the progress bar
        by default.
        * Animometer/resources/runner/animometer.js: Change default to 30 seconds.
        * Animometer/tests/resources/main.js: A number of improvements to the ramp controller, in
        the order in which they appear in the patch:

        - With a longer test length use longer ramps with longer intervals to get more data at each
        complexity. Keep the 100 ms interval length during the ramp up phase since we don't need to
        spend more time there to find the right order of magnitude, but increase it during the
        ramps to 120 ms.
        - The ramp linearly interpolates the complexity to render based on its timestamp, but it would
        never sample the minimum complexity. Instead of lerping max to min complexity from time
        0 to t where t is the ramp length, instead lerp from 0 to (t - intervalSampleLength) so that
        we can have at least one interval sample at the min complexity for that ramp.
        - Some regression calculations only come out with one line segment rather than the two
        we expect. This could be due to a noisy ramp or the ramp's range is too narrow. If that's the
        case, influence the minimum complexity of the next ramp towards the lowest bound of 1, so that
        we ensure that at least part of the ramp is covering a complexity range that the system can
        handle at full 60.
        - Remove an assignment to interpolatedFrameLength since that is never subsequently used.

        Update the format used to serialize the results for analysis.

        Each data point used to have named properties for fields like complexity and frame rate.
        In addition the serialized numbers had rounding errors that took up many characters.
        Update the format by introducing a new data container called SampleData, which contains a
        field map. The map maps a string to an array index. Each data point is an array, so, to
        get a stat, use the field map to get the array index into the data point. This allows future
        versions to track other data, and reduces the size of the output string by two-thirds.

        * Animometer/resources/extensions.js:
        (Utilities.toFixedNumber): Add convenience function that truncates the number to a fixed
        precision, and converts it back to a number.
        (SampleData): New class that contains sample data and a field map that maps properties to
        an array index.
        (get length): Number of data points.
        (addField): Add a field to the field map.
        (push): Add a data point.
        (sort): Sort the data.
        (slice): Return new SampleData object with sliced data.
        (forEach): Iterate over the data with provided function.
        (createDatum):
        (getFieldInDatum): Returns the data point associated with the field name by looking it up
        in the field map in the datum provided, which can be the datum object itself (an array) or
        an index into the data member variable.
        (setFieldInDatum): Sets the data point associated with the field name.
        (at): Returns the data point at the provided index.
        (toArray): Serializes the data where the field map serves as property names for each point.

        * Animometer/resources/debug-runner/graph.js:
        (updateGraphData): Remove unused _testData. Convert the data to the old array format for the
        graph to use, since the old format was much easier to work with when displaying the graphs.
        (onGraphTypeChanged): For some controllers, no alternative score or mean is provided.
        * Animometer/resources/runner/animometer.css:
        * Animometer/resources/runner/animometer.js: Refactor to use SampleData. Update JSON output

        * Animometer/resources/strings.js: Add new strings to put into the field maps.
        * Animometer/tests/resources/main.js: Refactor to use SampleData.

        (onGraphTypeChanged): Update score and mean if bootstrap results are available from the
        controller, since not all controllers do bootstrapping.
        * Animometer/resources/debug-runner/tests.js: Update header text.
        * Animometer/resources/runner/animometer.css: Include confidence interval in results.
        * Animometer/resources/runner/animometer.js:
        (ResultsTable._addHeader): Header contents can be HTML, so use innerHTML instead.
        (ResultsTable._addBody): Add tbody element.
        (ResultsTable._addTest): Allow a data cell to invoke a JS function to get its contents.
        (window.benchmarkController.showResults): Add table that includes tests' confidence intervals.
        * Animometer/resources/runner/tests.js:
        (Headers.details.text): Add new details table that includes bootstrap confidence interval.
        The interval can be asymmetric, but for simplicity, report the maximum deviation percentage
        on either side of the bootstrap median.
        * Animometer/resources/statistics.js:
        (bootstrap): Include the confidence percentage in the return object.

        Report canvas size in results.

        (window.benchmarkController.determineCanvasSize): Run various media queries and set the body
        class based on the size of the device.

        * Animometer/developer.html: Refactor to include the main CSS file, and redo
        the layout so that it doesn't rely on flexbox.
        * Animometer/resources/debug-runner/animometer.css:
        * Animometer/resources/debug-runner/animometer.js:
        (updateDisplay): Since various parts of the script alter the body class, we can't
        replace the className directly. Instead, remove all display-based values and then add
        the one that was selected.
        * Animometer/resources/debug-runner/graph.js:
        (updateGraphData): To set the size of the graph, use window.innerHeight.
        * Animometer/resources/runner/animometer.js:

        Introduce a different harness for run-jsc-stress-tests, which runs for a minimum of 10
        iterations and then tries to do any number of "bonus" iterations until it's been running for
        two seconds. Since this is the sort of test that isn't really meant to stress anything in
        particular, I think it's OK if it is time-limited in this way. The worst case is that some

        Use more ES6 features in JSAir
        https://bugs.webkit.org/show_bug.cgi?id=158497

        Reviewed by Keith Miller.
        
        This improves JSAir with the following ES6 features suggested by JoePeck:
        
        - String interpolation.
        - Destructuring inside PatchCustom.
        - Default arguments.
        
        All of these things are on hot paths.
        
        Note that I didn't use string interpolation everywhere that I could, only in those places
        where it made the code more readable. In Ruby, I used the style that if the interpolation
        expression has any non-trivial stuff (like a ternary operator, a chain of calls, or embedded
        strings) then it's better to use regular strcat. I think that's what I carried over to here.
        
        Note that the previous change (Add result validation to JSAir) also made the Proxy code not
        dead, though it's not necessarily on the hot path. The Proxy isn't called into frequently
        but it's used from a function that is otherwise hot, so if calling into the Proxy prevents
        that function from being optimized then it will hurt so good.
        
        I also reenabled tail calls in a few places.
        
        This change doesn't seem to change the performance of the benchmark for us. That's expected
        since these ES6 features are cheap. Note that this claim doesn't include Proxy, which was
        added in a separate change and that change did make the benchmark overall more expensive.

        This adds the ability to hash a Code in a way that matches the C++ code's hashing of Code.
        This allows us to check if the Code that JSAir sees is the code that C++ saw. We use this to
        check the Code before and after allocateStack, and compare against hashes we got from C++.
        
        Doing this uncovered bugs. roundUpToMultipleOf wasn't doing anything. allocateStack was not
        allocating things correctly because I was concatting a Set to an Array, which doesn't really
        work. Now these bugs are fixed.
        
        The checking step adds to the running time so I reduced the number of iterations. The
        benchmark spends a decent amount of its time computing Code hashes; I think it's around 1/3
        total. This is probably OK. It's better to verify the results even if the running time is
        not all in the "core" of the algorithm.
        
        Also add a run-jsc-stress-tests yaml file to allow this to run as a test.

        Implement Air::allocateStack() in ES6 to see how much of a bad idea that is
        https://bugs.webkit.org/show_bug.cgi?id=158318

        Reviewed by Saam Barati.
        
        This adds a new benchmark for us to play with called JSAir. It's a complete ES6
        implementation of Air's allocateStack() phase along with all of Air needed to run that
        phase. This includes things like stack slots, registers, temporaries, basic blocks,
        instructions, and all of the code for iterating over, inspecting, and modifying those
        things.
        
        To make this work, JSC can now dump Air just before allocateStack() in the form of JS code
        that creates a Code object that matches exactly what C++ Air saw. This benchmark comprises
        four Air IRs:
        
        - Octane/gbemu's largest function, executeIteration.
        - Kraken/imaging-gaussian-blur's largest function in OSR entry mode, gaussuanBlur.
        - Octane/typescript's largest function that is actually hot, scanIdentifier.
        - JSAir's largest hot function, which is anonymous, so we call it by its hash (ACLj8C).
        
        This runs in about 2 seconds on my machine in JSC trunk. It includes both a commandline
        harness and a web harness. JSAir is almost exactly 100x slower in ES6 in WebKit than the
        C++ Air::allocateStack() phase on which it is based.
        
        JSAir uses the following ES6 features:
        
        - Symbol.
        - for-of.
        - arrow functions.
        - Map/Set.
        - let/const.
        - classes.
        
        All of these things are used in anger and should end up on the hot path. There is also code
        that uses Proxies, but it ends up being dead.
        
        We can improve this even more:
        I still need to add result validation: https://bugs.webkit.org/show_bug.cgi?id=158493
        I want to make it use more ES6 features: https://bugs.webkit.org/show_bug.cgi?id=158497

        Reviewed by Stephanie Lewis.

        Two new files for the content-animation suite.

        After patching for use in the benchmark, these tests are a little different to other benchmarks.
        The test content itself does not collect performance data; the tests spit out a boilerplate JSON
        result with a placeholder for framerate, which is collected in native code.

        When run as a benchmark, test completion involves a couple of bounces between the test and MobileSafari.
        Test completion is initiated by a setTimeout() in the test, at which point location.hash is set to "#done".
        MobileSafari detects that, and asynchronously dumps performance data. Once this is complete, MobileSafari
        changes the URL has to "#submit", which triggers the XHR to the test relay that indicates the test is
        complete.

        Provisionally reviewed by Said Abou-Hallawa.

        * Animometer/tests/resources/main.js:
        (didFinishInterval): The ramp controller has a first phase where it ramps up the complexity and
        reacts based on how well the system handles the load. The assumption was that it would handle at least
        1 particle easily. That is not always the case. As a result, an interpolation calculation could
        end up setting an upper bound of NaN.

        This occurs because we never get out of the first tier, so this._lastTierComplexity is undefined.
        Now that we guarantee a minimum complexity of 1, modify the conditional to check for this._lastTierComplexity
        before interpolating the upper bound of the first ramp. In the case where the system struggles with
        1 particle, set it to currentComplexity.

        * Animometer/tests/master/focus.html: Move each particle into a layer. Put the particle
        in a container element. Expand the container element by the max blur radius, and clip
        overflow. This way, when the blur is applied, it avoids causing layer resizes.
        * Animometer/tests/master/resources/focus.js:
        (FocusElement.Utilities.createClass): Create a container element, and put the particle
        inside.
        (hide): Set display:none.
        (show): Set display:block.
        (animate): Apply filters to the container element.
        (FocusStage.call.initialize): Instead of inserting and removing elements from the DOM,
        keep them in the stage, but set the display style instead. Use this._offsetIndex to
        keep track of which elements are displayed.
        (FocusStage.call.animate): Move some calculations around to avoid doing unneeded math.
        (FocusStage.call.getBlurValue): Make sure elements are always blurred.
        (FocusStage.call.getOpacityValue): Make sure elements have some opacity.
        * Animometer/tests/master/resources/multiply.js: Have the particles on the edge of the
        stage appear less black when the complexity gets large enough.

        Update the ramp controller.

        The controller refines the complexity interval to test across.

        * Animometer/resources/statistics.js: Add functions that estimate cumulative distribution function.
        (Regression): For the flat regression, force the first segment to be at 60 fps.
        (valueAt): Add convenience function to return interpolated value based on the regression used.
        (_calculateRegression): Include the number of points included for both segments, and the piecewise
        errors.
        * Animometer/tests/resources/math.js: Make the Kalman estimator subclass Experiment, and allow it
        to be reset.

        * Animometer/tests/resources/main.js: Initialize the tier such that it starts at 10^0 = 1.
        Increase the number of ramps. Maintain three FPS thresholds-- the frame rate of interest, a limit
        on the lowest FPS we care to go for later interpolation, and a minimum FPS threshold we want to
        aim for each ramp. Also keep three estimators: a running average of the change point, a minimum
        boundary for each ramp, and an estimator for all the frames within an interval. The first two
        are used to determine the parameters of the next ramp, and the latter allows us to refine the
        parameters.
        (update): During the tier phase, it is possible that the highest complexity possible for a test
        won't stress the system enough to trigger stopping the tier phase and transitioning to the ramps.
        If the complexity doesn't change when going to the next tier, we've maxed the test out, and move
        on. When the tier phase completed, turn off Controller.frameLengthEstimator, which estimates the
        FPS at each tier.
        (tune): At each interval, look at the confidence distribution of being on the 60 FPS side or the
        slow side. If the slowest FPS we achieve at the ramp's maximum complexity is not at least
        _fpsRampSlowThreshold, then increase the maximum complexity. If we ever achieve 60 FPS, increase
        the ramp's minimum complexity to that level. If, at an even lower complexity, a glitch causes the
        FPS to drop, we reset the minimum complexity.

        Have the bootstrap calculation occur between tests. Clean up harness.

        * Animometer/resources/debug-runner/animometer.js: Run bootstrap after a test has
        completed to avoid doing all of it at the end before showing the results. Clean up
        parameters being passed around.
        * Animometer/resources/debug-runner/tests.js:

        serially. Grab the results object and move it to the results variable and remove it from
        the data object. This avoids serializing the results into the JSON.
        (this._processData.findRegression): Include the samples used for bootstrapping. Reduce the

        Use bootstrapping to get confidence interval in the breakpoint.

        For the ramp controller, calculate the piecewise regression, and then use
        bootstrapping in order to find the 95% confidence interval. Use the raw data.

        * Animometer/developer.html: Default to the complexity graph. Add a legend
        checkbox to toggle visibility of the bootstrap score and histogram.
        * Animometer/resources/debug-runner/animometer.css: Make some more space to show
        the old raw and average scores in the legend. Add new styles for the data.
        * Animometer/resources/debug-runner/graph.js:
        (_addRegressionLine): Allow passing an array for the variance bar tied to the
        regression line. Now |stdev| is |range|.
        (createComplexityGraph): Add bootstrap median, and overlay a histogram of
        the bootstrap samples. Switch raw samples from circles to X's.
        (onComplexityGraphOptionsChanged): Allow toggling of the bootstrap data.
        (onGraphTypeChanged): Move the regressions for the raw and average samples to the
        legend. In the subtitle use the bootstrap median, and include the 95% confidence
        interval.
        * Animometer/resources/runner/animometer.js:
        (this._processData.findRegression): Factor out the code that determines which
        samples to include when calculating the piecewise regression. For series that have
        many samples, or a wider range of recorded complexities, throw away the 2.5%
        lowest and highest samples before calculating the regression. Keep all samples
        if the number of samples to regress is small or the range of complexities is
        narrow.
        (this._processData._calculateScore): Factor out regression calculation to
        findRegression(). Bootstrap the change point of the regression. The score is the
        median.
        * Animometer/resources/statistics.js:
        (_calculateRegression): Correct an issue in the calculation of the regression, where
        the denominator can be 0.
        (bootstrap): Template for bootstrapping. Create a bootstrap sample array, Create
        re-samples by random selection with replacement. Return the 95% confidence samples,
        the bootstrap median, mean, and the data itself.
        * Animometer/resources/strings.js: Add bootstrap.
        * Animometer/tests/resources/main.js:
        (processSamples): Don't prematurely cut the sample data.

        Fix graph drawing.

        * Animometer/resources/debug-runner/animometer.js: Add spacing in the JSON output.
        Multiple tests output a lot of JSON and can hang when selecting JSON with no whitespace.
        * Animometer/resources/debug-runner/animometer.css:
        (#complexity-graph .series.raw circle): Update the color.
        * Animometer/resources/debug-runner/graph.js: Use the FPS axis instead of the
        complexity axis, which can vary in domain. For determining the complexity domain,
        only use samples after samplingTimeOffset.

        Allow dropping results JSON.

        * Animometer/developer.html: Add a button.
        * Animometer/resources/debug-runner/animometer.css:
        * Animometer/resources/debug-runner/animometer.js: Read the data and go straight
        to the dashboard. With JSON output, write out only the options and the raw data.

        Teach the harness to evaluate the samples and determine the test score.

        This will allow us to update how the score is calculated separately from the samples recorded.
        This also prepares the harness to be able to accept JSON of prior runs.

        * Animometer/resources/strings.js: Clean up and remove unneeded strings and reduce some of the
        hierarchy.
        * Animometer/resources/debug-runner/tests.js: Update to use the new strings.

        * Animometer/tests/resources/main.js: Allow all controllers to show a complexity-FPS graph.
        (_processComplexitySamples): Factor out some of the sample processing done in the ramp
        controller for the benefit of the other controllers. |complexitySamples| contains a list of
        samples. Sort the samples by complexity. Optionally remove the top x% of samples.
        Group them, and calculate distribution of samples within the same complexity, and add those as
        new entries into |complexityAverageSamples|.
        (Controller.processSamples): Move the code responsible for determining the complexity and FPS
        scores out to ResultsDashboard. The structure of the data returned by the controller is:

        {
            controller: [time-regression, time-regression, ...], // optional, data specific to controller
            marks: [...],
            samples: {                    // all of the sample data
                controller: [...],
                complexity: [...],        // processed from controller samples
                complexityAverage: [...], // processed from complexity samples
            }
        }

        (AdaptiveController.processSamples): Adding the target frame length is no longer necessary; we
        now pass the test options to the graph.
        (Regression): Move to statistics.js.
        * Animometer/resources/statistics.js: Move Regression to here. Add a check if the sampling range
        only contains one sample, since we cannot calculate a regression from one sample point.

        Teach the test harness to evaluate the data.
        * Animometer/resources/runner/animometer.js:
        (ResultsDashboard): Store the options used to run the test and the computed results/score separately
        from the data. The results are stored as:

        {
            score: /* geomean of iteration score */,
            iterationsResults: [
                {
                    score: /* geomean of tests */,
                    testsResults: {
                        suiteName: {

                                controller: {
                                    average:
                                    concern:
                                    stdev:
                                    percent:
                                },
                                frameLength: { ... },
                                complexity: {
                                    complexity:
                                    stdev:
                                    segment1:
                                    segment2:
                                },
                                complexityAverage: { ... }
                            },
                            testName: { ... },
                        },
                        ... next suite ...
                    }
                },
                { ...next iteration... }
            ]
        }

        * Animometer/resources/debug-runner/animometer.js: Pass options around instead of relying
        on what was selected in the form. This will later allow for dropping previous results, and
        using those runs' options when calculating scores.
        (ResultsTable._addGraphButton): Simplify button action by using attached test data.

        a new statistics.js, where Regression will also eventually go. Get rid of algorithm.js
        and move it to utilities.js since the Heap is used only for Experiments.

        * Animometer/tests/resources/algorithm.js: Removed. Heap is in utilities.js.
        * Animometer/tests/resources/sampler.js: Removed. Experiment is in statistics.js,
        Sampler in main.js.

            Added --no-warmup to not run the warm up iteration

        Changed the way that options are passed down to the benchmarks.  Instead of passing individual
        boolean or numeric option values, just pass a reference the CommandLine itself.  Each benchmark
        can access the options that are appropriate.  The Benchmark class also uses the options for
        is parallel, run counts and warm up.

        Added thread id and aligned malloc to the Op by noticing that structure padding and Opcode allowed
        for another 32 bits of data.  Breaking that unused 32 bits into a 16 bit thread id value and a
        16 bit log base 2 of the alignment for aligned malloc allowed for existing recordings to playback
        without any incompatibilities.

        Threaded operation is simulated by creating threads as needed.  As long as the next Op's thread id
        is the same as the last, operation continues as normal.  When the next Op has a different thread id,
        we switch to that thread using the shared Op stream to continue playing back.  There is a mutex to
        assure that only one thread is really running at a time and a condition variable used to wait
        that the current thread id matches each block thread's thread id.  This doesn't simulate true
        concurrent threading, but is instead plays back Ops recorded for multiple thread faithfully.

        Add a ramp controller
        https://bugs.webkit.org/show_bug.cgi?id=154028

        Provisionally reviewed by Said Abou-Hallawa.

        Enhance the graph to include a complexity-fps graph, in addition
        to the time graph.

        * Animometer/developer.html: Add a ramp option.
        * Animometer/resources/debug-runner/animometer.css: Update the style.
        * Animometer/resources/strings.js: Flatten the Strings.text constants.
        * Animometer/resources/debug-runner/animometer.js:
        (ResultsTable.call._addGraphButton): Refactor.
        (ResultsTable.call._addTest): Add regression data.
        (benchmarkController): Add a form that allows the user to switch between the two forms,
        Add a form that allows the user to toggle different data. Hide certain header columns
        depending on the selected controller.
        * Animometer/resources/debug-runner/graph.js: Add the complexity regressions.
        * Animometer/resources/debug-runner/tests.js: Add headers for the ramp results.
        * Animometer/resources/runner/animometer.js:
        (ResultsTable): If a header is disabled don't include them in _flattenedHeaders.
        * Animometer/tests/resources/main.js:
        (Controller): Allow options to specify the capacity for sample arrays.
        (Regression): A piecewise regression that tries to fit a slope and a flat profile.
        (_calculateRegression): Options can fix the slope and bias when calculating the minimal
        error. Sweep across the samples in time (which could be backward depending on the controller)
        and calculate the intersection point.
        (RampController): This controller assumes that the target frame rate is below
        58 FPS. It runs in two stages. The first stage quickly determines the order of
        magnitude of objects needed to stress the system by the setting the complexity
        to increasingly difficult tiers. Perform a series of ramps descending from a
        high-water mark of complexity. The complexity needed to reach the target frame
        length is done by performing a piecewise regression on each ramp, and track a
        running average of these values. For the next ramp, make that running average
        the center of the ramp. With a minimum complexity of 0, the high-water mark is
        twice that average. The score is based on the highest complexity that can
        reach 60 fps.

2016-02-08  Jon Lee  <jonlee@apple.com>

        Address Said's comments on the benchmark, and do some clean up.

        Strings constants.
        * Animometer/resources/debug-runner/graph.js:

        _suitesSamplers to _suitesResults.
        * Animometer/tests/resources/main.js:

        Teach Controller to measure intervals, and turn off the frame length estimator.

        * Animometer/tests/resources/main.js: Default interval length is 100 ms.
        (start): Set the first interval.
        (_measureAndResetInterval): Reports the average frame length of the interval that just
        completed, and sets up the next interval.
        (update): If there is no length, then just use the estimator per frame, otherwise the
        estimator measures per interval. Add a didFinishInterval for subclasses to process
        prior to recording the sample. Update tune() to include whether an interval had
        finished.
        (StepController): Step controllers don't measure on an interval basis.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Minor refactoring. Rename Controller._estimator to Controller._frameLengthEstimator
        and switch the parameters for start(), update(), and tune(), so that the timestamp

        Move ResultsTable functionality not needed for release tests out.
        Move reporting of score and mean to selection of the time-based graph.

        * Animometer/developer.html: Rename graph-options to time-graph-options.
        * Animometer/resources/debug-runner/animometer.js:
        (DeveloperResultsTable): Moved from runner/animometer.js. Switch from mean
        values to "average" objects which can hold stdev. Move graph button and
        calculation of noisy measurements here. Sophisticated header processing
        is not needed in release suite.
        (populateTable): Use DeveloperResultsTable.
        * Animometer/resources/debug-runner/graph.js: Pull time graph creation to
        its own function, and add a new onGraphTypeChanged handler in preparation
        of a complexity graph to be added later.
        * Animometer/resources/runner/animometer.js:
        (ResultsTable): Simplify to just handle test names and scores.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Tests: reuse objects already made.

        Avoid thrash of object creation and removal by maintaining an index that
        moves along the array as the adjust values change. If the tune value
        requires more objects than the maximum size of the object array, then create
        new objects. This means that the object array size never decreases.

        * Animometer/tests/master/resources/canvas-stage.js: Maintain a separate
        offsetIndex. For these tests, we want to avoid drawing the oldest objects,
        so the scene will draw the object at offsetIndex to the end of the array.
        (tune): Reverse the logic since "removal" of objects is much simpler and
        involves simply changing the offsetIndex.
        (animate): Update the for loop to draw from offsetIndex to the end.
        (complexity): Update the definition.
        * Animometer/tests/master/resources/canvas-tests.js: Maintain a separate
        offsetIndex. For these tests, we want to avoid drawing the newest objects,
        so the scene will draw the object at index 0 to the object at offsetIndex.
        (SimpleCanvasStage.animate): Fly-by removal of local stage variable,
        which is unneeded. Update the for loop to draw from offsetIndex to the end.
        * Animometer/tests/simple/resources/simple-canvas-paths.js:
        (SimpleCanvasStage.animate): Update the for loop to draw from 0 to
        offsetIndex.
        * Animometer/tests/simple/resources/simple-canvas.js:
        (tune): Update logic. Here, offsetIndex represents the boundary of the last
        index to render.
        (animate): Update the for loop to draw from 0 to offsetIndex.
        (complexity): Update the definition.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Tests: refactor and update styles.

        * Animometer/tests/resources/main.js: Add helper methods that return
        a color that hue rotates based on the date, and a counter value that
        increases based on the date. Fix randomInt() to not bias against the min and
        max values.

        * Animometer/tests/master/resources/canvas-tests.js: Use new helper methods.
        * Animometer/tests/master/resources/dom-particles.js: Ditto.
        * Animometer/tests/master/resources/particles.js: Ditto.
        * Animometer/tests/simple/resources/simple-canvas-paths.js: Refactor to
        use a rotating color instead of a random color. The fast switching of color
        is too vivid to watch.

        * Animometer/tests/bouncing-particles/resources/bouncing-svg-shapes.js:
        (BouncingSvgParticlesStage.call.createGradient): Fix the gradient so
        that the last stop is located at the end.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Refactor tune() to not return the complexity of the scene.

        We have stage.complexity() now, so returning the complexity through tune
        is unnecessary.

        Make the fixed controller a step controller instead. Halfway through the test
        it will bump up the complexity 4-fold. Calculate the step timestamp using options
        instead of a separate parameter to the Controller constructor.

        * Animometer/developer.html: Change value to "step"
        * Animometer/resources/debug-runner/animometer.js:
        (window.suitesManager.updateEditsElementsState): Show number inputs when set to "step".
        * Animometer/tests/resources/main.js:
        (update): Provide a hook for subclasses to tune.
        (StepController): Maintain a flag determining whether we've stepped, and the time
        we should step.
        (Benchmark): Use the new StepController.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Adjust the FPS graph scale.

        Instead of making the FPS graph linearly scale, scale it based on the frame length,
        but show the data in terms of FPS. Because it is inversely proportional, and most
        of the data never gets below 20, concentrate the axis from 20-60 FPS, since otherwise
        over half of the available graph space ends up blank.

        This means we should convert all of the FPS data to frame length data.

        * Animometer/resources/debug-runner/graph.js: Update the domain to be based on
        frame length in milliseconds instead of FPS. Update the cursor to consider all of the
        values being shown, and then pick the min and max values to represent the length of the
        cursor.
        * Animometer/resources/runner/animometer.js:
        * Animometer/resources/strings.js:
        * Animometer/tests/resources/main.js:
        (processSamples): Add the ability to only sample a range of the data instead of everything
        after an offset index. Update sampler to record the frame lengths instead of the frame
        rate.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Add option to use different methods for retrieving a timestamp.

        * Animometer/developer.html: Add performance.now and Date.now options.
        * Animometer/resources/runner/animometer.js: Default to performance.now.
        (window.benchmarkController.startBenchmark):
        * Animometer/tests/resources/main.js: Tie the desired method to _getTimestamp.
        (run): Use _getTimestamp.
        (_animateLoop): Ditto.

2016-02-07  Jon Lee  <jonlee@apple.com>

        Allow adding any number of markers to the graph. The markers can be labeled
        and contain timestamp and sample index data. Make it a part of the controller
        rather than keeping it in the sampler.

        * Animometer/resources/debug-runner/animometer.css: Add styles for markers
        * Animometer/resources/debug-runner/graph.js: Create the markers and add
        text labels.
        * Animometer/resources/runner/animometer.js: Assume the samplingTimeOffset
        is just one of the marks provided.
        * Animometer/resources/strings.js: Add Strings.json.marks.
        * Animometer/tests/resources/main.js:
        (Controller): Keep marks here. They are keyed by the marker name, so no two
        markers should have the same name.
        (recordFirstSample): Refactor to use mark.
        (mark): Allows for arbitrary data if needed later. The timestamp maintained
        is relative to the absolute start timestamp.
        (containsMark): Checks whether a mark with a specific comment exists.
        (processSamples): Removes the _startTimestamp offset from the marks before
        setting it in results.
        * Animometer/tests/resources/sampler.js: Remove marks.

        Update how the benchmark is run
        https://bugs.webkit.org/show_bug.cgi?id=153960

        Provisionally reviewed by Said Abou-Hallawa.

        Introduce the notion of a Controller. It is responsible for recording, updating,
        and processing the statistics and complexity of the benchmark. This allows
        plugging in different Controllers.

        This strips most of the functionality from Animator and BenchmarkState, so fold
        what's left into Benchmark. Now, Benchmarks only own a stage and a controller, but
        are responsible for driving the animation loop.

        Rewrite Animator._shouldRequestAnotherFrame into two different Controllers. One
        maintains a fixed complexity, and the other adapts the complexity to meet a
        fixed FPS.

        Fix the Kalman estimator to be modeled on a scalar variable with no model.

        * Animometer/tests/resources/main.js: Remove BenchmarkState and Animator, and
        replace it with a Controller. Add a FixedController and refactor the previous controller
        to an AdaptiveController.

        (Controller): Controllers own the estimator and the sampler. When a new frame is
        displayed, the animation loop calls update(). The estimator and sampler record
        stats, then tune. Samplers can track multiple series of data. The basic controller
        tracks timestamp, complexity, and estimated frame rate.
                The Kalman estimation is based on the frame length rather than the frame
        rate. Because FPS is inverse proportional to frame length, in the case where the measured
        frame length is very small, the FPS ends up being a wildly large number (in the order of
        600-1000 "FPS"), and it pulls the estimator up drastically enough that it takes a while
        for it to settle back down. Using frame length reduces the impact of these spikes.
                Converging the estimation takes enough time to avoid initializing it immediately
        when the benchmark starts. Instead, the benchmark runs for a brief period of time (100ms)
        before running it in earnest. Allow controllers an opportunity to set the complexity
        before starting recording.
                When the benchmark is complete, the controller has an opportunity to process
        the samples. The default implementation calculates the raw FPS based on the time
        difference of the samples, and calculates the complexity score. This is moved from
        Benchmark.processSamples.

        (Controller): Initialize timestamps. These are at first relative to the start of the
        benchmark, but are offset by the absolute start time during start(). By default maintain
        3 data series, but subclasses can override.
        (start): Calls recordFirstSample() for subclasses to override if needed.
        (recordFirstSample): For basic controller, start sampling at the beginning.
        (update): Update the frame length estimator and sample.
        (shouldStop): Checks that the time is before _endTimestamp.
        (results): Returns the processed samples.
        (processSamples): Iterate through the sample data and collate them. Include scores.

        (FixedComplexityController): Controller that tunes the stage to the desired complexity
        prior to starting, and keeps it at that complexity.

        (AdaptiveController): Have the estimator estimate the interval frame rate instead of the
        raw frame rate.
                The previous version of this controller ignored the frame that came after the
        adjustment. The raw FPS show that whatever noise the scene change adds is negligible
        compared to the noise of the system overall. Stop ignoring that frame and include all
        frames in the measurements.

        (Benchmark): Remove dependency on animator, and instantiate a runner based on what is
        selected. Most of the loop's functionality is in Controller, so remove here.
        (Benchmark.run): Remove start() since it is only called from run(), and fold it in here.
        (Benchmark._animateLoop): Fold in from Animator.animateLoop. Let the benchmark run for
        a brief period before calling Controller.start().

        * Animometer/tests/resources/math.js: Fix the Kalman estimator. The filter estimates
        a scalar variable, and makes basic assumptions regarding the model. As a result
        none of the linear algebra classes are needed, so remove Matrix, Vector3, and Matrix3.
        (SimpleKalmanEstimator): Calculate the gain based on the provided process and
        measurement errors.
        (KalmanEstimator): Deleted.
        (IdentityEstimator): Deleted.
        (PIDController): Refactor to use the Utilities.createClass() helper.

        The Kalman filter algorithm is explained here http://greg.czerniak.info/guides/kalman1/.
        The state, represented by a scalar, is the estimated frame length. There is no user
        transition of the state, and the state is the same as the measurement. With this model,
        the estimation error converges, so calculate the gain ahead of time.

        * Animometer/developer.html: Remove fixed-after-warmup since it is not useful.
        Replace the option to toggle the estimator, and make it possible to customize the
        estimator's error parameters. Show raw FPS by default, and remove interval FPS,
        which will be shown instead of the filtered raw FPS.
        * Animometer/resources/debug-runner/animometer.css: Put the header behind the graph.
        Remove #intervalFPS rules; move the color to #filteredFPS.
        * Animometer/resources/debug-runner/graph.js:
        (updateGraphData): Update the hr style to force the layout to be calculated
        correctly. Change the tick format to be in terms of seconds, since the timestamps
        are in milliseconds. Remove interval data.

        (window.benchmarkController.startBenchmark): Set Kalman parameters.
        * Animometer/resources/runner/benchmark-runner.js:
        (_runBenchmarkAndRecordResults): When a benchmark completes, expect it to return
        the final data, rather than passing a sampler from the controller. This avoids
        needing to expose the sampler variable in the benchmark.
        * Animometer/tests/resources/sampler.js:
        (process): Move the setting of the target frame rate to AdaptiveController.

        the same interval frame rate for adjustment.
        * Animometer/tests/resources/main.js:
        (Animator): Remove _dropFrameCount, and make variables more accurate described.
        (Animator.prototype.initialize): Use the identity estimator instead of using a bool.
        (Animator.prototype._intervalTimeDelta): Rename, only used internally.
        (Animator.prototype._shouldRequestAnotherFrame): Assume we drop one frame for adjustment
        of the scene. If we are within the number of frames to measure for the interval, just
        record the timestamp. Otherwise we are ready to evaluate and adjust the scene. Record
        the interval frame rate and the estimator's frame rate.

        Avoid processing the data through the Experiment while the test is running. Reconfigure
        the sampler to just record the raw samples. After the test is done, run the samples through
        the Experiment to get the score.

        * Animometer/resources/sampler.js:
        (Experiment): Fold _init() into the constructor since nobody else will call it. This is not
        needed until the test concludes, so remove startSampling(). Clients should just call sample().
        (Sampler): Pre-allocate arrays given the number of data points being recorded, and a capacity
        of how many samples will be used. The processor is a called when it's time to process the data
        since that is the client also telling the Sampler what to record.
                Introduce the notion of marks as well, which allows the client to mark when an
        event occurs. When we mark sample start, we can attach the timestamp there, instead of storing
        it separately.
        (Sampler.prototype.startSampling): Deleted. Clients should just call record().
        (Sampler.prototype.record): The data to record is passed in as variable arguments.
        (Sampler.prototype.mark): When adding a mark, a client needs to provide a unique string, and
        can provide extra data object for later retrieval.
        (Sampler.prototype.process): Renamed from toJSON. Trim the sampling arrays to what was used.
        Call the processor to process the samples.
        * Animometer/resources/debug-runner/benchmark-runner.js:
        (BenchmarkRunner.prototype._runBenchmarkAndRecordResults): Call process().

        * Animometer/resources/strings.js: Add some new strings, remove the graph ones since they are
        not used.
        * Animometer/tests/resources/main.js:
        (Benchmark): Create a sampler with 4 series. The maximum number of points expected is the
        number of seconds multiplied by 60 fps. Benchmark, as a client of the Sampler, knows about all
        of the data being added to the Sampler. It is added through record(), and processed through
        processSamples().
        (Benchmark.prototype.update): Mark when we've passed warmup and are starting to sample. Include
        the timestamp in the custom data for the mark. This avoids the need to store is separately in
        the Sampler. Fold what was in record() here, since nothing else needs this functionality.
        record() now just relays the information to the sampler.
        (Benchmark.prototype.record): Called by Animator, which provides the data to the sampler.
        Animator's calls to this is part of a later patch. Requires each stage to return its complexity.
        (Benchmark.prototype.processSamples): If the sampling mark exists, add it to the results.
                Go through all of the samples. All samples contain a timestamp and complexity. We
        calculate "raw FPS" which is the time differential from the previous sample. At regular intervals
        the Kalman-filtered FPS and the interval average FPS are also recorded. We also create two
        experiments, to get the scores for the complexity and smoothed FPS, and add those samples to
        the experiments. Grab those scores and add them into results also.

        Add complexity() to the tests for Benchmark.record().

        Add newer version of harness in a new page. Consolidate differences between the two
        pages.

        * Animometer/developer.html: Include runner/animometer.js. Rename the JS function
        to run the benchmark to startBenchmark() instead of startTest(). Rename #running to
        #test-container.
        * Animometer/index.html: Added. Similarly calls startBenchmark() and has #test-container.
        * Animometer/resources/debug-runner/animometer.css: Make the canvas 2:1 (1200px x 800px)
        instead of 4:3.

        Split out benchmarkRunnerClient and benchmarkController.

        * Animometer/resources/debug-runner/animometer.js: Move needed functions out of
        benchmarkRunnerClient, and leave the rest here to extend that object. Get rid of _resultsTable
        and move populating the results table into benchmarkController. Rename _resultsDashboard
        to results and make it accessible for other objects to use.
        (willAddTestFrame): This is unnecessary. Remove.

        (window.sectionsManager.showScore): Grab it from the results object instead of
        benchmarkRunnerClient.
        (window.sectionsManager.showSection): Deleted. Moved to runner/animometer.js.

        (window.benchmarkController._runBenchmark): Deleted. Mostly moved into _startBenchmark.
        (window.benchmarkController.startBenchmark): Refactor to call _startBenchmark.
        (window.benchmarkController.showResults): Include most of benchmarkRunnerClient.didFinishLastIteration()
        here.

        * Animometer/resources/debug-runner/benchmark-runner.js:
        (BenchmarkRunner.prototype._appendFrame): Remove unneeded call to willAddTestFrame.
        * Animometer/resources/extensions.js:
        (ResultsDashboard): Change the class to process the sampler data on-demand and hold onto that data
        for later referencing.
        (ResultsDashboard.prototype.toJSON): Deleted.
        (ResultsDashboard.prototype._processData): Rename toJSON to _processData since it's not really
        outputting JSON. Store the processed data into a member variable that can be referenced later.
        (ResultsDashboard.prototype.get data): Process the data if it hasn't already.
        (ResultsDashboard.prototype.get score): Process the data if it hasn't already, then return the
        aggregate score.
        (ResultsTable.prototype._showHeader): When outputting the results to a table, don't force the
        need for an empty children array. This was to allow for a header row in the table that spanned
        multiple columns. In the simpler harness, this is not needed.
        (ResultsTable.prototype._showEmptyCells):
        (ResultsTable.prototype._showTest): This hardcoded the columns. At least for the name and score,
        which is the bare minimum needed for the simpler harness, key off of the header name provided.
        * Animometer/resources/runner/animometer.css: Added. Use a similar 2:1 ratio. The score tables are
        split into the data and the headers, and are also displayed RTL so that a later patch allows a
        user to copy-paste the data easily.
        * Animometer/resources/runner/animometer.js: Added. Use a simpler version of benchmarkRunnerClient.
        The debug harness will extend these classes.
        (window.benchmarkController._startBenchmark): Used by both harnesses.
        (window.benchmarkController.startBenchmark): Set hard-coded options.
        (window.benchmarkController.showResults): Includes most of benchmarkRunnerClient.didFinishLastIteration()
        here.

        Generate the checkboxes representing the suites using Suites
        instead of maintaining a separate list. Also, save the
        selections out to localStorage.

        * Animometer/runner/animometer.html: Remove the explicitly listed
        suites. These will be generated from Suites instead.
        * Animometer/runner/resources/animometer.js:
        (populateSettings): Iterate through Suites, and create the
        label and checkbox. Attach the Suite object to the checkbox so
        when the benchmark is started, we get direct access. Initialize
        the checkmark based on its value in localStorage. Set this to
        run when DOMContentLoaded is dispatched.
        (startBenchmark): Grab all of the checkboxes, inspect their
        values, add it to enabledSuites if selected. Remember whether
        the suite was enabled in localStorage, so that it's easy to do
        repeated runs.
        * Animometer/runner/resources/tests.js:
        (Suite): Create a new Suite class. Refactor out prepare() and
        run(), since all of them have the same implementation. Populate
        Suites with Suite instances instead of generic objects.

        Instead of measuring the FPS of the animation, this benchmark measures the
        test complexity when rendering at a set-point FPS which should be lower
        than 60 FPS. This benchmark tries to stay at the set-point FPS by using
        a closed loop control system PID function. The gain of the system is passed
        as a parameter when running the test. Measuring the FPS faithfully results
        very fluctuating values. A Kalman filter is used to give a better estimate
        for the current FPS.

        The animation of the tests is done manually. requestAnimationFrame() is
        called with a callback. Inside this callback, the test is animating by
        changing the positions of the elements inside the page. The test complexity
        may change also if the current FPS is not equal to the desired FPS.

        In this patch, the benchmark and the tests are included. The shared code
        and the tests runner are included in separate patches.

        [JetStream] Raise the percentile of mandreel-latency and splay-latency
        https://bugs.webkit.org/show_bug.cgi?id=146378

        Reviewed by Mark Lam.

        The current percentile is 95%.  When I looked at the sample lists in our GC, it was
        clear that the worst 5% samples completely amortize our GC pauses.  Our GC pauses can
        be quite bad.  Clearly, splay-latency is meant to test whether we have an incremental
        GC that ensures that you don't have bad worst-case pauses.  But 95% is too small,
        because it doesn't really capture those pauses.  Raising the percentile to above 99%
        appears to do the trick.  99.5% or more seems like a good bet.  The trade-off there is
        just that if we set it too high, then we won't have enough statistics.  Doing this very
        clearly rewards GCs that are incremental, and punishes GCs that aren't (like ours).
        That's what we want, since in the future we want to use this test to guide any
        improvements to the worst-case performance of our GC.

        The way that the percentile is selected will also affect mandreel-latency.  That's a
        good thing, because 95% is probably too low for that test as well.  That test ends up
        with >10k samples.  The goal of using 95% in the first place was to get enough samples
        to have a stable average.  But if we have >10k samples, we can push that percentile up
        much higher and still get good statistics while achieving the effect we want - i.e.
        getting the worst case.

        I don't think that we need to do the same thing for cdjs.  That test only takes 200
        samples, so 95% means we report the average of the worst 10 samples.  That's probably
        good enough.

        JetStream should include a JavaScript version of the CDx real-time benchmark
        https://bugs.webkit.org/show_bug.cgi?id=146156

        Reviewed by Geoffrey Garen.

        This adds a JavaScript port of the CDx real-time benchmark to JetStream, and retires
        the cordic test because it was previously the smallest and probably least interesting.

        The new test, "cdjs", is mostly a faithful rewrite of the Java code into JavaScript.
        I got the Java code from https://www.cs.purdue.edu/sss/projects/cdx/.

        There are some differences:

        - It uses RedBlackTree's for all sets and maps rather than hashtables. This is clearly
          more in the spirit of real-time than the CDx benchmark. FWIW, CDx used to use trees
          and I don't know why that changed in the latest version.

        - CDjs doesn't attempt to avoid memory allocations, unlike the real-time Java version.
          I wrote the code that I wanted to write for aesthetics, rather than the code that I
          would have written if I tried to write the fastest code possible. Again, I believe
          that this is in the spirit of CDj - it's meant to test what would happen if you wrote
          real-timey stuff in a high level language and actually took advantage of that
          language to be more productive.

        The test score reflects the average latency of the worst 10 samples out of 200 samples.
        The simulation uses 1000 aircraft, flying along paths that result in some detected
        collisions every once in a while. The benchmark validates its results by checking the
        total number of collisions detected.

        Apart from the integration into the JetStream harness, the CDjs directory contains a
        fully self-contained benchmark that could be run either in the jsc shell or in browser.

        This new code uses the same 3-clause BSD license as the Purdue code, and gives
        attribution to Purdue in almost all files. I believe that is appropriate since I wrote
        most of the JS files by looking at the Purdue Java code and trascribing to JavaScript.
        In some cases, I even copy-pasted the Java code, like the complicated math for
        four-dimensional intersections and voxel hashing.

        JetStream should have a more rational story for jitter-oriented latency tests
        https://bugs.webkit.org/show_bug.cgi?id=145762

        Reviewed by Geoffrey Garen.

        JetStream has some latency tests that are meant to measure jitter.  Prior to this change, they
        did this by computing the RMS.  But the RMS is a pretty bad metric.  The thing that it rewards
        isn't really the thing that you'd want your browser to do.  These RMS-based tests involve taking
        the geomean of the RMS of some samples and the sample average.  The lower the geomean, the better
        (in the JetStream harness we then invert the scores so that higher is better, but let's ignore
        that for this discussion and assume that lower is better).  Here's an example of how this can go
        bad.  A browser that always computes a task in some horribly long time (say, 1000ms) but never
        varies that time will perform better than a browser that usually computes the task super quickly
        (say, 10ms) and sometimes just a little bit less quickly (say, 15ms).  The former browser will
        have an RMS of 0 and an average of 1000.  The latter will have a RMS somewhere around 3.5 and an
        average of 12.5 (assuming equal probability of 10ms and 15ms).  The geomean of (0, 1000) is 0.
        The geomean of (3.5, 12.5) is 6.6.  Lower is better, so the former browser scores higher - even
        though it's obviously never better to have a browser always complete a task in 1000ms when a
        different browser can do it in 15ms in the worst case.

        JetStream should not have this pathology.  The right way of avoiding it is to replace RMS with
        some other metric of how bad things get.  A good metric is the average of the worst percentile.
        The worst 1% or the worst 5% would be good things to average.  This will catch cases where the VM
        jittered due to JIT or GC, but it never have the pathology that we end up giving the better score
        to a VM whose best case is worst than another VM's worst case.

        For now, this change uses the highest samples above the 95% percentile. I'm not yet sure if that
        is the best thing - it might include too many scores that are around the best-case performance -
        but it's certainly better than RMS and it might be good enough to keep. But because of that
        uncertainty, I'm setting the version to be "1.1-alpha1" to indicate that we aren't ready to
        release this yet.

        DYEBench should run 20 iterations in browser
        https://bugs.webkit.org/show_bug.cgi?id=132795

        Reviewed by Gavin Barraclough.

        Right now, run-perf-tests runs BYEBench 4 times with different instances of DRT/WTR to get
        a more stable time and account for differences in the runtime environment, particularly,
        ASLR (Address Space Layout Randomization).

        While we can't account for the latter effect when the benchmark is ran inside a browser,
        we can at least run 20 iterations to get a more stable (but perhaps biased by ALSR) number.

        While the sample size of 20 is statistically unsound to compute the arithmetic mean from,
        it's MUCH better than the current sample size of 5.

        LongSpider 3d-morph result check is inappropriate.

        Reviewed by Filip Pizlo.

        The LongSpider 3d-morph component expected result check is incorrect.
        The existing test checks if the leading digit of a sum starts with "-1".
        However, it turned out that the expected sum is in the order of
        -1.8735013540549517e-16 (i.e. very close to 0).  With small errors in
        the terms of the sum adding up, it is very easy for the resultant sum
        to fluctuate.  There is no guarantee that the resultant sum's most
        significant digit will start with -1 either.

        The fix is to do a tolerance check on all the terms of the sum as well
        as the total sum value instead.  The tolerance should be more lenient
        for the sum which accumulates error from the individual terms, then for
        individual terms.

        (.): Moved the initialization of completedIterations, results, jsHeapResults, and mallocHeapResults into
        start since they need to be initialized before running each subtest. Initialize logLines here since we
        need to use the same logger for all subtests.
        (.start): Initialize the variables mentioned above here. Also respect doNotLogStart used by reportValues.
        (ignoreWarmUpAndLog): Added doNotLogProgress. Used by reportValues since it reports all values at once.
        (finish): Compute the metric name such as FrameFrame and Runs from unit. Also don't log or notify done
        when continueTesting is set on the test object.

        Introduce a version of SunSpider that runs for a really long time (about 1 sec on my machine)

        Rubber stamped by Mark Hahnenberg.

        to see how these benchmarks behave when they're completely warmed up.

        Reviewed by Sam Weinig.

        The goal of this benchmark is to have an overview of querySelector as typically used
        by webpages.

        It uses queries similar to what is used by popular websites and applies somewhat
        similar weighting for each type of query.

        The tree used for the queries is intentionally kept simple to ensure we measure QuerySelector

        Web Inspector: Split Profiler domain in protocol into Profiler and HeapProfiler

        Currently CPU and heap profilers share the same domain 'Profiler' in the protocol.
        In fact these two profile types have not too much in common. So put each into its own domain.

        Made one small modification to Droameo's webrunner.js so that it reports individual runs/s values
        for each subtest. This allows us to compute the aggregated run/s for each iteration like other
        performance tests.

        Also stop measuring memory usage in Dromaeo tests because some Dromaeo tests (e.g. jslib-modify-jquery)
        have unrealistic memory usage, and measuring them at the time of teardown doesn't make much sense.

        the iframe as the first child of the body element to avoid logs from affecting the iframe's position.
        Also specify the number of iterations by calling PerfTestRunner.iterationCount() so that we may adjust
        the number of iterations in PerfTestRunner.

        (DRT.progress): Log individual measurement for each subtest.
        (DRT.teardown): Compute the aggregated result for each iteration, and log them using measureValueAsync.

        Reviewed by Tony Chang.

        Prior to this patch, there were terminology confusions between "runs" and "iterations".
        The term "run" should refer to running a performance test once, and "iteration" should
        refer to one measurement in the test. i.e. Executing run-perf-should once will result in
        a single "run" of performance tests and each test may execute multiple "iterations"
        to complete the run.

        Unfortunately, we still overload the meaning of "runs" in "runs/s" (is "function calls/s")
        but that could be addressed in a separate patch.

        Previously, our PageLoad PerfTests had multi-modal distributions,
        typically with a small cluster at 1-2x the median. This turned out
        to be caused by not garbage collecting between tests!

        This patch adds a new file, force-gc.html, and loads this file between
        PageLoad tests to force a GC. I manually verified that this cleans up

        The new test tries to stress detaching on a heavy subtree (2 levels deep but with 1,000 nodes per level).
        We set display: none on the root and measure the time it takes to update the tree. Note that we will also
        measure the time taken by recalcStyle and relayout but I don't think we can avoid that.

        Previously our standard deviation calculation was incorrect. This patch

        http://en.wikipedia.org/wiki/Algorithms_for_calculating_variance#Online_algorithm
        An existing test has been modified to prove our new results.

        This patch also updates runner.js to use Bessel's correction in
        its sample standard deviation calculation, which is more accurate
        for small sample sizes.

        Additionally, runner.js has been modified to not calculate

        Results page should warn about time-dependent distributions
        https://bugs.webkit.org/show_bug.cgi?id=97818

        Reviewed by Ojan Vafai.

        Add a simple linear regression analysis on results page to detect time-dependent distributions.
        We add a warning sign (inline SVG) when the regression gave us a slope of at least 0.01 and a R^2 of at least 0.6.
        Also added time-series graphs per run under the bar graphs so that humans can manually inspect them.

        A nice follow up would be to add some normality test (e.g. Shapiro-Wilk) to detect bi-modal distributions
        but we probably need to restructure the code to run it asynchronously since normality tests are slow.

        Web Inspector: serialize edge counts instead of indexes in heap snapshot
        https://bugs.webkit.org/show_bug.cgi?id=88324

        The serialized node structure currently holds an index
        of its first containment edge in the edges array.
        The index can be quite big (up to 7 digits for large snapshots).
        The patch changes the serialization format to pass
        node containment edge count instead. For most nodes the count
        is just a single digit number.
        This reduces serialized snapshot size and therefore its transfer time.

        reasonable micro benchmarks by classifying DOM binding call paths.

        This patch adds a benchmark for document.getElementById() for an undefined id.
        This benchmark covers 'getElementById (not in document)' in Dromaeo/dom-query.html,
        and other Node-query methods that return a null.'

        (Note: This benchmark is slower than document.getElementById() for a defined id.
        We will fix the performance issue soon.)

        [perf-test] Add a binding benchmark for getElementById()
        https://bugs.webkit.org/show_bug.cgi?id=86808

        Reviewed by Ryosuke Niwa.

        Currently Bindings/dom-attributes.html is just a collection
        of random DOM attributes and methods. We should remove it and
        instead add more reasonable micro benchmarks by classifying
        DOM binding call paths.

        This patch adds a benchmark for document.getElementById(),
        which covers other DOM methods that return a Node Object.

        The reason why we want to add a benchmark for document.getElementById()
        in spite of the fact that Dromaeo/dom-query.html is already testing
        document.getElementById(), is that Dromaeo/dom-query.html outputs one
        result for several benchmarks (i.e. getElementById().nodeType,
        getElementsByTagName()[0].nodeType etc), and thus we cannot observe
        regression of getElementById() itself. (Catching regression of
        getElementById() would be critical.)

        Use runPerSecond instead of run to measure results in function calls per second (run/s) instead of time (ms).
        This allows us to continue measuring performance reliably even when WebKit's performance improves and results
        become too small for Date.now()'s precision (around 15 ms).

        It should also reduce perf. bots cycle time for slower tests because we limit the number of function calls by time.

        Reviewed by Ojan Vafai.

        Add PerfTestRunner.runPerSecond. It uses _runLoop but replaces _runner by _perSecondRunner
        to compute runs/s of runFunction.

        When _perSecondRunner is called for the first time, i.e. _completedRuns is 0 (notice this is -1
        in regular run/_runner), it slowly increases the number of function calls to runFunction between
        time measurements in order to discount the time used by new Date() calls themselves until the
        total time spent reaches 100 milliseconds.

        By default, runPerSecond runs the test for at least 750 milliseconds in each run, and executes
        21 runs, yielding the total run time of roughly 18 seconds. This is significantly faster than
        most of existing performance tests. Also see http://ejohn.org/blog/accuracy-of-javascript-time/.

        Finally, refactored the existing methods of PerfTestRunner to allow "runs/s" unit and share code.

        [PerformanceTests] run-perf-tests should output correct units
        https://bugs.webkit.org/show_bug.cgi?id=78303

        Reviewed by Ryosuke Niwa.

        Previously run-perf-tests just supported "ms" for units.
        Consequently, Dromaeo perf tests had been reporting runs/s as "ms".
        This patch fixes run-perf-tests so that they can support custom units.
        The default unit is "ms".

        The test result looks like this:

        Reviewed by Hajime Morita.

        Dromaeo perf-tests had reported the sum of runs/seconds as "ms".
        This patch fixes them to report the execution time per run.

        At present, they report "0.0ms" for "stdev". This is because
        dromaeorunner.js can just know stdev of "runs/seconds"
        and cannot calculate stdev of "ms" from that. We can fix it later.

        This patch halves the execution time of Bindings/dom-attributes.html
        in order to avoid timeout in Chromium. The reason for the timeout is that
        V8 DOM bindings are too much slower than JSC bindings.
        I am a bit afraid that this patch will reduce the accuracy of the
        perf test results, but it would make sense to reduce the execution time
        until we fix the performance issue in V8 DOM bindings.

        Unreviewed.  The patch is too large to post, so landing this unreviewed. :(

        The copy of the html5 spec we were using for testing was over a year old
        and didn't have any of the subresources with it (we were only using it
        as an HTML parsing benchmark).  I'm about to use it for testing
        the full load/render time of the benchmark, so I've updated to the latest
        version of the spec (now 8mb instead of 5mb) and inlined two of the
        CSS files.  (Inlining the CSS was necessary to make my testing consistent
        as there seems to be a race with some timer fired after CSS load.)

        Increasing from 5mb to 8mb showed a similar 30% slowdown in our parser
        benchmarks as expected.

        PerformanceTests/Parser/html-parser is only testing parsing of the head element
        https://bugs.webkit.org/show_bug.cgi?id=69283

        Reviewed by Adam Barth.

        While investigating https://bugs.webkit.org/show_bug.cgi?id=68944
        I found that the html-parser benchmark was only parsing up to the
        first script tag per loop!  We've fixed this by adding the sandbox
        tag which will deny all external loads and allow the parser to
        synchronously continue parsing the entire document to completion
        (as we had expected it was doing).

        This changes the profile somewhat.  Line number counting is much
        hotter, since we're actually accounting for the parse of the entire
        document in our sample.

        Total sample time only about doubles, from 1800ms to 3800ms on my machine
        which is less than I would have expected.

        https://bugs.webkit.org/show_bug.cgi?id=53845

        The final-url-en URL corpus is from:
        http://corpus.leeds.ac.uk/internet.html

        There are also other language corpuses which we may want to use in the future.

        The usage instructions were as follows:
        "URL lists and other resources: you can freely use them in your research
        provided that you supply a link to this website: http://corpus.leeds.ac.uk/."
        Done.

        * Parser/simple-url.html: Added.

        It's silly to have ChangeLogs for each of these directories separately.

        It's unclear exactly what the Peacekeeper benchmark is testing,
        because I haven't found a way to run it myself.

        However, I constructed a benchmark which shows at least one possible slow point.
        The HTML5 spec talks about creating a new document for every time we use

        To avoid constructing (or destructing) documents for each innerHTML call,
        this patch adds a shared dummy document used by all innerHTML calls.
